How/why we use this chemical
-PCDD were once used as electrical insulating and heat exchange fluids
-“Assay was then used to assess cross-reactivity by congeners of halogenated dioxins and related structures.”
Specific products it’s in
• Some Fish
• Butter
• High Fat Foods
• Eggs
• Animal Fats
• Milk
• Wild Life
• “They are found in commercial chlorophenols and their derived products, emissions from incineration sources, and byproducts from pulp and paper mills.”
What it does (positives)
Polychlorinated Dibenzo-p-Dioxins are byproducts of manufacturing plastic. So with out it there wouldn’t be any plastic.
Where it is used (what countries)
• -Japan
• -Taiwan
Human health implications
Possible dangers:
• It can cause skin conditions.
• They’re very toxic.
• Can cause kidney failure.
• Cancer (liver, lung, palate/tongue)
Specific processes
-Human systems that can get affected are, in blood, lipid tissues and breast milk.
-They accumulate in fat and liver.
Environmental implications
What happens when it degrades?
It does not disappear completely.
How long does it take to degrade?
It depends what its in. For instance if it’s in a human well it would take about a few minutes an hour or two. To degrade completely not so sure.
How is it disposed of?
The dioxins are disposed by slowly being metabolized by oxidation. Also bile and feces excrete them.
Economic/Political Impact
What if it were banned?
PCDD’s are banned in the US but there are still imports of it.
Cost of alternatives?
What products would we not have if it were banned?
Even though the chemical is banned we sill receive all the products we get from it because we get it imported from other places.
How/If a ban affects you (or the average American)
There would not be that much of a problem because we would get it imported from different places.
What are the political ramifications of banning this chemical?
It is banned.
3. Synthesis/Production
How it’s made
Polychlorinated Dibenzo-p-dioxins are byproducts of burning wood and making plastics.

Abstract
Polychlorinated Dibenzo-p-dioxins (PCDD’s) are byproducts of burning wood and plastic. PCDD”s have been banned from the US, but we still get imported from different places. PCDD’s are toxins and are found in many place and caused by many things, like before, burning wood and
Before when they were not banned they would get in the water and contaminate fish and fish would contaminate us by us eating them. PCDD’s can cause kidney failure, skin conditions, and cancer. That is if you have enough so it reacts.
I think that where PCCD’s stand is a great idea. Being banned is good because for one it can cause fewer effects on people and for that then less deaths or serious health conditions.
Summary
Poly chlorinated dibenzo-p-dioxins are environmental pollutants. There are not good for humans and if they get in our bodies enough there will be serious health damages. Over all these dioxins are banned and yet are still imported from other places. There are many types of dioxins and they have effects on humans. If there banned in the US there are most likely to be imported from somewhere else.
